Application flied november s, 191e. serial No: 798,791.

To all whom 'it may concern Be it known that I, BURNS D. LooKwooD, -a citizen of the United States, residing at 141 Sprague avenue, Bellevue, in the countyand exact description, such as will enable others skilled in the art to which it appertains to make and use the same,reference doein'g had to the accompanying drawings,

forming-part of this specification.

An object vof the present invention is to provide a railway car underframethat is l light and strong and which can be manufactured at low cost, and vwhich is especially adapted for use in boX car construction, but

.which may be used in any other classes of cars where suitable.

Another object of the present invention is to reduce toa minimum the number of parts of which the underframe is composed, with a consequent lreduction 1n the number of securing means employed for connecting such arts. 4 A further object o f the present invention is toprovide-a car underframein which the bolster comprises a single element, entend-V ing preferably from side'ton side ofthe underframe and forming a connecting medium between the; center and draft sills, thebol-jfster being provided with suitable portions to which the center sill and 4draftsi'll mean-A bers areconnected.

' A specic object 'of-the present invention is to. provide axbolster'member which ex* tends from side to' sideof the' underframe, in the central portionof which is combined the center brace, together Iwith provision for receivingthe king pin, and also a converging web portion suitable for connection to the l'center sill, and projecting-portions to which'the draft sills may be secured.

With these: and other objects in view, the present. invention consists in the combination and arrangement of parts, as "will be'. lhereinafter more fully described, shown onthe.` accompanying drawings, and V'particularly pointed out inthe appended" claims,

it being understoodthat changes in the form, proportion, size 'and minor details. maybe made, within the scn'pe of the claims,

' 'i a more rigid connection-between thece'nter without departing from .the spirit or sacrificing any of the advantages of thelinvention.

Referring now to the drawings, in which 'i like reference'char'acters refer to like parts and in which Fig. 1 is a plan view of a pon' tion of an under-frame embodying the invention; Fig.` 2 is -a'sectional view taken on the line 2 2 of Figjllg Figs,` 3, 4 and 5are .cross sectional views on thelines 3 3, 4-4

and 5 5 respectively of Fig. 1 and Fig. 6'

is an enlarged detail sectional view on the line 6 6 of Fig. 2.

Referring now in detail to the drawings, A

. 1 indicates the center sill which may be of rolled I beam section, or as 'shownin the sevin cross section fora. greater part of its length. The outer ends of this bolster' member are provided with flanges 6, 6, to which theside sills 7 7- are secured. Beyond `the 'side sills these outer ends are provided with extension portions 8, 8, the undersides of which forni` bearing surfaces for jacks whenV it is desired to lift the car from its trucks. These extension portions-are provided with openings 9, 9, through which la rope may be'V passed when it is desired to shift the car by such means. From a point on either side of the longitudinal center .line of the car, the web portions'10, 10 of the bolster 5 `converge toward said center line in a direction" toward the transverse center line-of the car,

and-on the opposite vsideJ is provi-dedv with, lugs 1'1, 11,'to which thedraft sills 12, `12

`are secured, such draft sills being also secured tothe end v sill .13 by any suitable vmeans. 'These lugs and converging portion. of the bolster are strengthened bythe verti- .cal rib 141,'the,hori7'ontal ribs 15, top flanges 16, 1 7 and by "the bottom flanges 18, 1 9.v The top flange' 1G and .the bottom flange 1S may be substantially alike, .having portions to 'which the draft sills are secured. The top iange 17 and the bottom flange'19 may be substantially alike, and. have portions 20 to which the tension and compression' members of the center sill are secured. To form ico les

sill'and the bolster, members 21, 21 of any suitable form are provided which are riveted or otherwise secured and the center sill. l

The cross beams 92 are preferably of rolled form and extend from' side to side of" the car, the end portions` forming seats for the side sills 7. lVhere the crossbeam passes through the web of the center sill, bracket members L3, 233 are provided which are secured to said cross beam and web.

In the several drawings` only one end of the underframe has been shown, but it will be understood that the other end is substantially the same in all respects.

Having thus described the invention what I claim as new and desire to secure by Letters Patent 1s e 1. An underframe comprising a single ing a. wedge shaped web portion intermedi-.

ate its ends, of a single center sill framed into said bolster element, and means for `connecting said members.

fl. In a railway car underframe, the combination with a single bolster element having a V-shaped web portion of a single center sill framed into said bolster member and means secured to said sill and V-shaped portion for connecting all of said members.

5. In a railway car underframe, the combination with a single rigid bolster element having lugs extending in one direction, and a central V-shaped portion extending in the opposite direction, of draft sills secured to said lugs and a single centersill secured to said V-shaped portion.

6. An underframe comprising a single rigid bolster element inrcombination with a single center sill and a pair of d 'aft sills, said bolster element having a V-shaped web portion.

7. In a railway7 car underframe, the combination with a single rigid bolster elementi having a wedge shaped portion and lugs 1ntermediate its ends, of draft sills secured to said lugs, a single center sill and means for securing said center sill to said wedge shaped )ortion of said bolster.

8. A bolster of substantially I shape in cross section having a wpdge'slliaped web to both the bolster-- cross section having, intermediate its ends, f

a. wedge shaped web extending in one directionand lugsv extending 1n the yopposite direction, a center sill connected with said web, and draft sills secured to said lugs.

11. A' bolster of substantially I- shape in cross section .having a wedge shaped web portion intermediate its ends and means for strengthening said wedge shaped' web portion, a center sill, and means for connecting -said web and sill together.

12. A bolster of substantially l' shape in cross section having a wedge shaped web portion intermediate its ends and ribs for strengthening said wedge shaped web portion, one of said ribs having an opening formed therein for the reception of a king pin, a center sill, and means for connecting said web and sill together.

18. In a railvvay car underframe, the combination with a bolster having a V shaped web'portion intermediate its ends, a center sill terminating short of said V shaped web portion, and angular members connecting said center silland V shaped web portion.

14. In a ,railway car underframe, a bolster member having a V shaped web portion intermediate its ends, said V shaped web .portion extending in a direction toward the transverse centerline of thev underframe, lugs extending fromsaid web portion in a direction toward the end of the under-fname, draft sills secured to said lugs, a center sill terminating short of said V shaped web portion, and angular members adapted -to connect said Vsill and web portion. I

15. In a railway car underframe,` a bolster having a vertical web and horizontal top and" b.ottom flanges on each side of said web, lugs projecting from said web, draft sills terminating short of said web and secured to said lugs and horizontal top and bottom flanges on one side of the web, the center sill terminating short of said web and secured to said top and bottom ges of the otherside of s'aid web, and angular members connecting said center sill and web of said bolster.

In testimony whereof I aliix my signature in presence of two witnesses.
